An example of an elective unit in Senior Science:

Year 10 Genetics and Forensics

Who Murdered Mr. Hall ???

Students use techniques learned during their time in genetics and forensics to examine a "crime scene" and deduce who the murderer is.

Suspect 1  Ms Rachael Radvanyi Job: Acting Deputy (shared). Green Staff Room. Access: Has keys to the Main Staff Room . Motive: ???? Comment:  I am devastated by Michael Hall’s death.

Suspect 2 Ms Lyndall Henman Job: Acting Deputy (shared). Red Staff Room. Access: Has a key to the Main Staff Room. Motive: ???? Comment: I wonder who will be Principal now? Thank God I don’t drink coffee.

 You may be able to work this out by deduction.
Was there a faint smell of almonds???
His death was certainly NOT natural causes.
IT WAS MURDER!!!
